ABSTRACT

A webbing roller suitable for being coupled to a portion of a webbing, drooping after an effective length of the webbing is adjusted. The webbing roller includes a pair of webbing roller bodies; an opening defined at first ends of the webbing roller bodies and having a retainer band which is connected to the first ends of the webbing roller bodies around the opening; and a fastening projection formed on second ends of the webbing roller bodies to allow the retainer band to be fastened thereto.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates, in general, to a roller for arranging awebbing, and more particularly, to a webbing roller which allows aportion of the webbing of a bag, a knapsack, a baby carrier, etc.,drooping after a user adjusts the effective length of the webbing to fithis or her body, to be tidily arranged.

2. Description of the Related Art

In general, webbings are used in bags, knapsacks, baby carriers, etc.for ensuring convenience in use.

A webbing means a woven material having a certain width. In detail, thewebbing indicates the material which is frequently used through ourlives for the seat belt of a vehicle, the chin strap of a safety helmet,a collar for a dog, clothes, a bag, a knapsack, etc.

The webbing can be integrally attached to a bag, a knapsack, etc. tohave a fixed length or can be used along with an adjuster such as abuckle member to be freely adjusted in the effective length thereofdepending upon the physical constitution of a user.

That is to say, when a user carries a bag or a knapsack on the shoulderor by the hand, if the user feels that the effective length of a webbingis too long so it is inconvenient to carry the bag or knapsack, theeffective length of the webbing can be adjusted by manipulating thebuckle member.

However, in this case, referring to FIG. 1, as remaining portions ofwebbings 10 droop with substantial lengths, the outer appearancesthereof deteriorate, and it is difficult to arrange the remainingportions of the webbings 10. Also, when the effective length of thewebbing 10 is adjusted using the buckle member, the effective length ofthe webbing 10 is likely to abruptly increase or decrease by inadvertenttouch to the webbing 10.

In order to cope with this problem, in the conventional art, Velcrobrand hook and loop fastener strips are stitched to the webbings 10 sothat the webbings 10 can be tidily arranged using the Velcro brand hookand loop fastener strips with the drooping portions of the webbing 10rolled up. Nevertheless, even in this case, when the webbings 10 areused for an extended period, the corners of the Velcro brand hook andloop fastener strips are likely to be worn out so that the outerappearances of the webbings 10 deteriorate, and the adhesion force ofthe Velcro brand hook and loop fastener strips is likely to decreasewith the lapse of time. Also, as the Velcro brand hook and loop fastenerstrips adhere to clothes, the clothes are likely to be damaged.

As a result, in the conventional art, when the effective length of awebbing is adjusted using a buckle member, a remaining portion of thewebbing droops, whereby the outer appearance of the webbing candeteriorate. Also, since it is difficult to appropriately arrange theremaining portion of the webbing, the effective length of the webbing islikely to abruptly increase or decrease by inadvertent touch to thewebbing.

SUMMARY OF THE INVENTION

Accordingly, the present invention has been made in an effort to solvethe problems occurring in the related art, and an object of the presentinvention is to provide a webbing roller which allows a portion of awebbing, drooping after adjusting the effective length of the webbing,to be tidily arranged so that the outer appearance of a user's body, abag, a knapsack, etc. can be improved.

In order to achieve the above object, according to the presentinvention, there is provided a webbing roller suitable for being coupledto a portion of a webbing, drooping after an effective length of thewebbing is adjusted, the webbing roller comprising a pair of webbingroller bodies; an opening defined at first ends of the webbing rollerbodies and having a retainer band which is connected to the first endsof the webbing roller bodies around the opening; and a fasteningprojection formed on second ends of the webbing roller bodies to allowthe retainer band to be fastened thereto.

Among these drawings, FIG. 2 is a perspective view illustrating theentire construction of a webbing roller 100 in accordance with anembodiment of the present invention, which is suitable for being coupledto a portion of a webbing, which becomes useless and droops after theeffective length of the webbing is adjusted, FIG. 3 is a perspectiveview illustrating a state in which a retainer band 200 is coupled to thewebbing roller 100 according to the present invention.

Referring to FIGS. 2 and 3, the webbing roller 100 in accordance withthe embodiment of the present invention, which is to be coupled to awebbing, includes a pair of webbing roller bodies 190 which are formedparallel to each other at the center portion of the webbing roller 100,a first wing 150 which is formed on the first ends of the webbing rollerbodies 190 and is defined with an opening 110 around which a retainerband 200 is to be connected, and a second wing 170 which is formed onthe second ends of the webbing roller bodies 190 and is formed with afastening projection 120 to which the retainer band 200 is to befastened.

A slit 130 is defined between the pair of webbing roller bodies 190. Anend of the webbing can be passed through the slit 130 and can be coupledto any one of the webbing roller bodies 190 through stitching.Depressions and prominences can be formed on the webbing roller bodies190 so as to prevent the webbing from slipping on the webbing rollerbodies 190.

The first wing 150 and the second wing 170 are formed parallel to eachother. The pair of webbing roller bodies 190 are formed to be placed atpositions which are separated by a predetermined distance from both endsof the first wing 150 and the second wing 170 formed parallel to eachother. As a consequence, with the end of a portion of the webbing, whichbecomes useless and droops after the effective length of the webbing isadjusted, passed through the slit 130 and coupled to any one of thewebbing roller bodies 190 through stitching, the useless portion of thewebbing can be wound around the webbing roller bodies 190 by rotatingthe webbing roller 100. The first wing 150 and the second wing 170,which are formed parallel to each other, perform a guiding function inthe widthwise direction of the webbing so that the webbing can be evenlywound around the webbing roller bodies 190.

The first wing 150 is defined with the opening 110 around which theretainer band 200 is connected. At least one opening 110 can be definedto have a circular or elliptical sectional shape.

The opening 110 of the first wing 150 is defined outside the middleportion of the first wing 150 so that the retainer band 200 can beconnected to the first wing 150 around the opening 110. Firstprotrusions 140 are formed on the middle portion of the first wing 150in such a way as to protrude sideward between the first ends of the pairof webbing roller bodies 190.

The fastening projection 120 is formed on the middle portion of thesecond wing 170. The fastening projection 120 is formed to projectoutward from the middle portion of the second wing 170 so that theretainer band 200 connected to the first wing 150 around the opening 110can be fastened to the fastening projection 120. By crossing theretainer band 200 over the useless portion of the webbing which is woundaround the pair of webbing roller bodies 190 and then fastening theretainer band 200 to the fastening projection 120, the useless portionof the webbing can be held wound on the webbing roller 100.

The fastening projection 120 is formed to have a neck part 180 which hasa reduced thickness so as to allow the retainer band 200 to be reliablykept fastened to the fastening projection 120. Preferably, the fasteningprojection 120 is formed to have the substantial shape of a mushroomsuch that one portion thereof to hold the retainer band 200 becomesconcave and the other portion thereof not to hold the retainer band 200has a larger width so as to prevent the unintentional release of theretainer band 200.

Second protrusions 160 are formed on the middle portion of the secondwing 170 in such a way as to protrude sideward between the second endsof the pair of webbing roller bodies 190.

The first protrusions 140 and the second protrusions 160 are formed tohave a height that is greater than the thickness of the useless portionof the webbing wound around the pair of webbing roller bodies 190 sothat the webbing can be evenly wound in the vertical direction when theuseless portion of the webbing is wound around the pair of webbingroller bodies 190 by rotating the webbing roller 100 after the end ofthe webbing is passed through the slit 130 and coupled to any one of thewebbing roller bodies 190 through stitching.

Also, a fixing holder can be additionally formed around the fasteningprojection 120 so as to prevent the retainer band 200 from beingreleased. The fixing holder can be formed integrally with the webbingroller 100 and can function to prevent the retainer band 200 from beingreleased from the fastening projection 120 after the retainer band 200is fastened to the fastening projection 120.

Referring to FIG. 3, the retainer band 200 is connected to the first endof the webbing roller 100 which defines the opening 110. A procedure forconnecting the retainer band 200 to the first wing 150 of the webbingroller 100 around the opening 110 is as described below. The first endof the retainer band 200 is inserted through the opening 110 of thewebbing roller 100. When the first end of the retainer band 200 isinserted half, the second end of the retainer band 200 is insertedthrough the first end of the retainer band 200. Then, by pulling thesecond end of the retainer band 200, the first end of the retainer band200 is connected to the first wing 150 of the webbing roller 100 whichdefines the opening 110. It is preferred that the retainer band 200 bemade of an elastic material having a certain degree of contractibility.

In the webbing roller 100, the first protrusions 140 formed on the firstwing 150 and the second protrusions 160 formed on the second wing 170function to guide the webbing to be evenly wound in the verticaldirection when winding the webbing around the pair of webbing rollerbodies 190.

FIG. 4 is a plan view illustrating the webbing roller 100 according tothe present invention. It is ideal for maintaining the elasticity of theretainer band 200 that the first protrusions 140, which are formedadjacent to the opening 110, have a height 400 of 1.5˜2.5 mm,preferably, 1.7˜1.8 mm when measured from the outer surfaces of thewebbing roller bodies 190. The second protrusions 160 are formed to havethe same height as the first protrusions 140 when measured from theouter surfaces of the webbing roller bodies 190.

FIG. 5 is a view illustrating a state in which a portion of a webbing,drooping after the effective length of the webbing is adjusted, iscoupled to the webbing roller 100 according to the present invention.

A procedure for coupling the useless portion of a webbing 500 to thewebbing roller 100 through the slit 130 is as described below. After theend of the webbing 500 is inserted through the slit 130, a predeterminedlength of the webbing 500 is pulled out in a direction opposite to theinsertion direction, and the end of the webbing 500 is stitched to apart of the webbing 500 so that the webbing 500 is firmly coupled to anyone of the webbing roller bodies 190 and then the useless portion of thewebbing can be wound around the webbing roller bodies 190.

FIG. 6 is a view illustrating a state in which the webbing is arrangedby means of the webbing roller 100 according to the present invention.

With the remaining drooping portion of the webbing coupled to thewebbing roller bodies 190 through the slit 130, the remaining droopingportion of the webbing is wound on the webbing roller 100 by rotatingthe webbing roller 100. After the webbing is wound on the webbing roller110, the webbing is fixedly retained by fastening the second end of theretainer band 200, which has the first end thereof connected to thewebbing roller 100 around the opening 110, to the fastening projection120.

FIG. 7 is a view illustrating an exemplary application of the webbingroller 100 according to the present invention to a knapsack. A remainingportion of a webbing, which becomes useless and droops after theeffective length of the webbing is adjusted in a knapsack, is tidilyarranged using the webbing roller 100 (see the reference numeral 700).As a consequence, it is possible to prevent the drooping portion of thewebbing deteriorates the outer appearance of the webbing. Also, due tothe presence of the webbing roller 100 according to the presentinvention, it is possible to solve the problem which is caused in theconventional art by the fact that the effective length of the webbing islikely to abruptly increase or decrease by inadvertent touch to thewebbing when the effective length of the webbing is adjusted with theknapsack carried on the shoulder.

As is apparent from the above description, the webbing roller accordingto the present invention provides advantages in that, since a portion ofa webbing, drooping after the effective length of the webbing isadjusted, can be tidily arranged, it is possible to prevent the outerappearance of the webbing from deteriorating.

Also, when the effective length of the webbing is adjusted using abuckle member or the like, it is possible to prevent the adjusted stateof the webbing from being spoiled due to unintentional increase ordecrease in the effective length of the webbing by inadvertent touch tothe webbing.
